It's 1987. The Metropolitan Police are waging an intimidation campaign against London's LBTQ+ community.

Wearing rubber gloves to "protect from AIDS" they raid the Royal Vauxhall Tavern

"Well well," says Lily Savage (Paul O'Grady) from the stage as the police pile into the venue. "It looks like we’ve got help with the washing up" /1

The raid was one of a number carried out by the police, using obscure laws as justification for their intimidation.

In this instance, the excuse was "reports of drunkenness on premises"

With Lily continuing to mock the police, she was handcuffed and arrested with others. /2

@garius drunkenness on a private property is a crime?
@mcfly @garius yes, drunkenness in a pub is a crime (Licensing Act 1872 s 12 https://www.legislation.gov.uk/ukpga/Vict/35-36/94 ), possibly two because a publican must not serve alcohol to drunks (Licensing Act 2003 https://www.legislation.gov.uk/ukpga/2003/17/part/7/crossheading/drunkenness-and-disorderly-conduct ).
Licensing Act 1872
